Nitrogen dioxide: The formula of nitrogen dioxide is NO2. Nitrogen dioxide is a gaseous air pollutant. It is produced by combustion of fossil fuels. The presence of nitrogen dioxide in air leads to the formation of other air pollutants, like ozone and particulate matter which in turn leads to acid rain. This gas is also the primary pollutant.

Among the given options CO2 (carbon dioxide) doesn't pollute air. We exhale CO2 and it is utilised by plants in photosynthesis

[@waqassakhakot1996]

thermal conductivity decrease with the rise in temperture

[@adnansardar9166]

Because of increase in resistance?

[@mariaarif4325]
